Surface morphology effects on droplet spreading and rebound dynamics on subcooled superhydrophobic surfaces by Matic Može, Yuheng Shang, Samo Jereb, Nina Kovač, Miha Štucin, Tim Štrus, Peter Rodič, Matevž Zupančič, Maria Rosaria Vetrano, Iztok Golobič

“…Droplet impact tests were performed at Weber numbers between 50 and 185 and across surface temperatures from 25 °C to -30 °C. Surface morphology had a minimal effect on the maximum spreading factor, which was otherwise found to decrease by up to 9.5% when reducing the surface temperature from 25 °C to -30 °C. …”

Compensating cooling on the suction surface of the blade by the jets of the film holes on the endwall by Changyu Zhao, Junyu Zhu, Wei Zhang, Zhiqi Zhao, Guangchao Li, Chun Li

“…The coolant ejected from the film holes on the gill region of the blade deflects to the blade tip in the action of the cascade passage vortices, resulting in the local film cooling failure on the suction surface near the endwall. This paper introduces an improved strategy for compensating the film cooling on the suction surface near the endwall by using the passage vortices to entrain coolant inject from endwall jet. …”

EFFECT OF MULTIPLE ULTRASONIC NANOCRYSTAL SURFACE MODIFICATION ON SURFACE INTEGRITY OF 304 STAINLESS STEEL by MA YunRui, LIAN Yang, LI ZhiKun, YE ZhongFei, LI Yang

“…The ultrasonic nanocrystal surface modification(UNSM)technique can build a strengthened layer with good surface integrity on the metal surface,and this layer improves the mechanical properties of metals.The effect of multiple UNSM on the surface integrity of 304 stainless steel was investigated,and a good strengthened layer was obtained.The surface of 304 stainless steel sample was strengthened by multiple UNSM technique,and the strengthened layers with different depths were prepared on the surface of the material.The hardness gradient,residual stress gradient,microstructure gradient and surface morphology of the sample were measured by using the microhardness tester,X⁃ray residual stress analyzer,3D morphometer and metallographic microscope.The results show that the grain size of 304 stainless steel is obviously refined after multiple UNSM treatment,and the thickness of the strengthened layer increases with the increase of treatment times.Comparing with the untreated sample,after two times of UNSM treatment,the residual stress on the surface of the sample increased from-156 MPa to-425 MPa,the depth of residual compressive stress reached 0.7 mm,and the surface microhardness increased from 185 HV0.2 to 350 HV0.2.The results show that the UNSM technology can build a deeper strengthening layer,but it needs to be optimized.…”

Testosterone pellet surface area relates to effectiveness more than dose by Charles Virden, Michelle Mays

“…The goal of the study was to evaluate the effect of pellet dose versus surface area on blood levels over 3 months in healthy men.Methods One group of men were administered small individual pellets that resulted in higher surface than the other group, but at a lower dose.Results Within 2 weeks the T levels had risen over two times the baseline level in both groups, but the cohort administered the lowest T dose (but highest surface area) had the greatest response whether calculated as peak change or when analyzed according to age-adjusted values. …”

Langmuir Turbulence Effects on Coastal Surface Waves by Jiehua Wu, Peng Wang

“…Due to the difficulty in resolving Langmuir turbulence in ocean models, its effect is usually parameterized. In this study, we implement a Langmuir turbulence parameterization into a coupled wave–circulation model and use it to investigate the effects of Langmuir turbulence on the evolution of surface waves under upwelling-favorable wind conditions over an idealized continental shelf. …”
